Dear Radon Leaders:
An Excel copy of the data contained in the EPA/State Residential Radon Surveys conducted between 1987 and 1992 is available. This data has been used by EPA in a variety of ways over the years, including construction of the EPA Map of Radon Zones. Radon researchers and others may find this data useful. This data previously was only available from the NTIS (www.NTIS.gov). The data is statistically significant at the state level. EPA conducted the surveys in 42 states; eight states conducted independent surveys (DE, NH, NJ, FL, IL, NY, OR, UT). Short-term screening measurement test results for about 60,000 homes comprise the data set. Most state data sets have five calculated county-level values based on a varying number of measurements, i.e., mean, geometric mean, median, standard deviation and maximum. Three states have data below the county-level: Delaware (DE) data is at the zip code level; no county-level data; New Hampshire (NH) has only town-level data; and, Virginia (VA) has city-level data for 33 cities, and county-level data. You may obtain a copy of the data from your EPA Regional Office radon representative, or from Phil Jalbert/EPA HQ (Jalbert.philip@epa.gov)(EPA-SRRS 1987-1992 PJalbert 30-JAN-2014.xlxs.xlsx; 225KB).
Thanks,
